Identify WMS Layer in Pro

I'm having difficulties identifying features in a WMS layer in ArcGIS Pro. I can see that a request is sent off to the service, but ArcGIS does not show results. I used Fiddler to inspect the result, and found that ArcGIS passes invalid coordinates for the I and B parameters:

 

/bag/ows?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetFeatureInfo&CRS=EPSG:28992&BBOX=136560.0620867619,456692.50642435468,136818.65103321758,456895.75946457294&WIDTH=1215&HEIGHT=955&LAYERS=verblijfsobject&QUERY_LAYERS=verblijfsobject&STYLES=&EXCEPTIONS=XML&FORMAT=image/png&INFO_FORMAT=text/html&FEATURE_COUNT=50&I=-641613&J=214651

 

Since both I and J are pixel coordinates (see § 7.4.2 of the specs), they cannot possibly be negative, and yet ArcGIS passes -641613 and 214651. And even if by accident ArcGIS used real-world coordinates, they would still be invalid due to the fact that the used spatial reference does not have negative coordinate values...

 

The service is http://geodata.nationaalgeoregister.nl/bag/ows?SERVICE=WMS&VERSION=1.3.0

The map uses the RD New spatial reference (EPSG:28992), and so does the WMS layer.
